摘要： A pre-verifying method for software/hardware design of a communication system includes simulating a process of sending a data frame from a transmitter to a receiver with a transceiver algorithm meeting a preset specification for obtaining simulation parameters. A transmitter hardware platform sends the data frame via an antenna. A receiver hardware platform receives an echo signal of the data frame and compares each parameter of the echo signal with the simulation parameters. The comparison result of various parameters of the echo signal and the simulation parameters is verified to be in a desired range or not. When the comparison result is not in the desired range, the transceiver algorithm is adjusted. When the comparison result is in the desired range, the transceiver algorithm is converted to a hardware program language format to be written in a programmable module to perform the action of the transmitter and the receiver.

摘要： The present invention discloses a method for predicting fast fading using sinusoidal modeling techniques. The method first applies a finite impulse response low pass filter to the incoming signal thus increasing the fading power to noise ratio. Applying a root-MUSIC frequency estimation model, a sinusoidal model for the fading process is obtained. This model can be used to enhance the performance of spatial diversity schemes or temporal processing schemes to reduce the effect of the fading.
